The most potent source of Vitamin D is the sun. Although to be more accurate, it is the action of the sun's energy on melanin in human skin actually produces the Vitamin D. Given the easy access to sunlight, it would seem that of all vitamins, this is one that we would never need to introduce in supplement form into our diets. And yet, this is not necessarily the case.

Vitamin D, or cholecalciferol, is a fat-soluble vitamin that is necessary for maintaining strong, healthy teeth and bones and for protecting against bone abnormalities such as rickets, bone-loss conditions such as osteoporosis and skin problems such as psoriasis. It does this by helping to regulate calcium and phosphorus absorption in the body.

Despite the ease of acquiring adequate levels through exposure to the sun, several factors can result in inadequate serum vitamin D levels in the average American. The elderly are predisposed to the effects of low vitamin D due to a predominantly indoor lifestyle, particularly those who are confined to nursing homes or where illness precludes outdoor activities.

Similarly non-white Americans are also at risk due to increased pigmentation, which effectively reduces the amount of vitamin D that can be produced in the skin. One study showed that over 40% of African-American women were found to have a vitamin D deficiency compared with 4.2% of white American women. The increasing trend of indoor employment and leisure activities over the last few decades has also had a profound effect on the ambient vitamin D levels of all Americans.

Worldwide studies, including those conducted at Boston University, the University of Bonn in Germany, the University of Toronto and the University of South Carolina to name a few, have clearly outlined the case for increased vitamin D supplementation. Vitamin D deficiency has been linked to heart disease, autoimmune disorders, depression, hypertension, multiple sclerosis, diabetes, and other serious disorders.

In view of the lifestyle changes due to workplace and leisure practices, together with an aging population, vitamin D supplementation now forms an important part of a healthy lifestyle.

Vitamin D should not be taken by individuals suffering from elevated serum calcium levels or hyperparathyroidism without consulting a physician.
